  With my HTML lib I wrote for Ruby:


  #!/usr/local/bin/ruby

#-*-Ruby-*-
require 'HTMLoop'


doc = HTMLdoc.new(H_title => 'Ruby HTMLoop Example',
		  H_address => '[e-mail]')


doc << h1("Larger header")
doc << h2("Smaller header")


myTable = HTMLtable.new(H_border => 3, H_bcolor => '#dd9999')


# Array of rows and columns.
foo = [['Column 1', 'Column 2', 'Column 3'],
       ['Larry',    'Moe',      'Curly']]


myTable << foo

doc << myTable

puts doc



  If there is sufficient interest I will put together some documentation
  and make it available.
